ful .Supp'brt for Pa er Fed to Printing-a Presses, of which the ollowing is a specildcas 1 tion.

This invention relates to means for sir i porting any number of upper sheets of a e" of paper fed to a printing-press from. the bot,- torn by suction or otherwise, th'eobj ect of the invention being to provide an apparatus for this purpose which will be simple in construction and require little attention.-

Referringto thedrawings, 1 indicates a paper-feed frame adapted to; support a pile of sheets for feedingtliem to sprinting-press.

This frame is'paused to reciprocate with the reciprocatin cylinder at-the rear. end of the movement the. latter that is, when taking the aper; f The construction 'hepessary 'fordliicing" this. movement of the frame-beingin commonuse is not-here shown v The frame lfisi formed with threeysiots' 2, extendii% centrally and at back anc two sides of the frame, the front "side thereof, at which the paper istaken, being unslotted.

v Secured by-cl'ainpscrews 3 1n said slots are bases 4;, nponeac. of which stand a stout square inner post and a siened at the top by across-piece Hafiz-rm ariupper bearing for ashalt 8, which extends down through the base and carries at" itslower end a bev'ehgear 9. These threebevel-gears 9 mesh with bevel-gears 10 11, the two bevel gears 10 being adjustably mounted on asqu'are transverseshaft 12, extending under 'the'frame [1 and entirely-across the same,

and the bevel gear '11 being mounted on.

Y shorter square shaft 13, also beneath the frame 1, but at right angles to the shaft 12, said shaft 13 being driven from, the shaft 12 bye pair of bevel-gears 3. .2 The bases 45 are moved along the slots and the hevelgears 10 ii are correspondingly moved along right angles tothe l hese are connectthe shafts l3 and read listed to correspond .with. the dimensions of t e sheets inthe pile of aper to be fed.

To revolve the shaft 12 intermittently in unison with the operation of the press,'there is{ mounted upon the end of said shaft 3. ratchet-wheel 16, which is advanced by a .'pawl 17, pivoted on a'lever 18, having holes 19, whereby it may be connected with the bed 20 of the printingpress. ineans intermittent revolution, to keep pace with the feed of the sheets tothe press, is imparted to all of the shafts Ssimultaneously. Each shaft 8 is threaded, exce t for a short distance immediately above the ass, and cooperating with said shaft are a number of suitably-spaced separator-carriers 21, each having a half round internally threaded socket or recess 22 to fit the threaded shaft 8 and act as a half-nut. The carrier has at the rear of the recess 22 a curved recess 23 toreceive the post 6. In the carrier slides asepa- 4 rater 24L, normally retracted by a spring- 25, coiled. around the separator and compressed By the above l between. the carrier and the head 2610f the in position, they are placed on the top of the placed upon them, the separators being cortheirdesired notches 27 engage the edges of position by the engagement of the notch 27. with the-lip -28, of the threadedrecess 22 with'the threaded shaft 8, of the recess 23 with the post 6, and by the pressure of the spring 25; Thereafter as the shafts 8 interinittently' revolve the separators slowly descend, keeping pace -With the feed of the she'tsirona the bottom. r Byaneans' of the separators on the three ofthe upper sheets is removed from the lowest sheet, so. that the latter can easily be drawn out. At the sametirne the separators can easily be putin or taken out at any time in case of emergency.

When the separator arrives at the bottoni oi the shaft 8, it is no longer upheld by the v threads of the shaft, and since the notch no longer engages thelip 28, which. does not reach to LJQVG out cribs-ck, which. it does under the acpile of sheets, and other sheets are then the, lips,28.' Each separator 18 then held in '7 sides at suitable verticaldistances the Weight,

chase 4, the separator is free to respondingly moved into such position that tion of the spring'25,until stopped by shoulders 29 on the separator coming to the front face of the carrier. The separatoris then discharged by means of an internal gearwheel 30, revolved by a gear 31 on the shaft 8, said gear 30 being mounted in peripheral.

bearings consisting of pins 32 entering a groove 33 in the periphery of the gear-wheel. Said gear-wheel 31- carries a lug 34, which as it revolves engages the separator and moves it with it, the tongue of the separator then entering a curved channel or guideway 35.

-As the separator is carried around with the gear its rear end engages a stop-36, arresting the revoluble movement of said rear end, so that the front end still being carried round the separator is discharged to the rear. Thus all the separators are so discharged auto-- matically until all the paper is used. By this means one man} can attend to three or four machines. While one press is working he can be filling up the paper-feed of the next machine and at the same time placing the separators in position.

Any number of such separators can be used and any amount of paper placed upon the feed-frame conditioned upon the power used to draw the sheets of paper from the bottom.

I clairn 1. In an apparatus of the character described, in combination with a reciprocatory element of a printing-press, a frame, posts thereon, separatorsextending by the sides of said posts inward into the pile of sheets,

means for supporting said separators in such position, and means for lowering the separators, while so supported, said latter means being operated in unison with the reciprocatory element, substantially as described.

' 2. In an apparatus of the character described, in combination with a reciprocatory element of a printing-press, a frame, vertical screws supported thereby, separators extending inward to penetrate the pile of sheets,

means whereby said separators are.supported by said screws, and means for turning said 'screws, in unison with the movement of the reciprocatory element, to lower said-separa- 5o tors, substantially as described.

3. In an apparatus of the character described, in combination with a reciprocatory element of a printing-press, a frame, vertical screws supported thereby, means whereby said screws can be adjusted to different locations on said frame for different sizes of paper, separators extending inward to penetrate the pile of sheets, means whereby said separators are supported by said screws, and means for turning said screws, in unison with the movement of the reciprocatory element, to lower said separators, substantially as described. l

4. 'In an apparatus of the character described, in combination with a reciprocatory element of a printing-press, a frame, vertical screws supported thereby, separators extending inward to penetrate. the pile'of sheets, means whereby said separators are supported by said screws, means for turnin said screws, inunison with the movement 0 the reciprocatory element, to lower said separators, and

means whereby said separators are automatically discharged on arriving at the bottom of the screws, substantially as described.

5. In anapparatus ofthe character described, in combination with a reciprocatory element of a printing-press, a frame, vertical screws supported thereby, separators extending inward to penetrate'the pile of sheets, carriers for supporting said separators, formed with a half-nut to engage the corresponding screw, and means for turning said screws, in unison with the movement of the reciprocatory element, to lower the separators, substantially as described.

6. In an apparatus of the character described, in combination with a reciprocatory element of a prin tingpress, a frame, vertical screws supported thereby, separators extending inward to penetrate the pile of sheets, means whereby said separators-are supported by said screws, means for turning said screws, in unison with the movement of the reciprocatory element, to lower the separators, and

means, operated by the continued movement of the latter means, for discharging said separators when arriving at the bottom of the screws, substantially as described.
